No unusual procedures are required. Note any sensor wiring and vacuum lines at the pump. Bracket design varies depending on model and equipment fitted and may require removal or adjacent components for access.

Remove the pump drive belt.

Place a drip pan beneath the power steering pump and disconnect the hoses. Cap the hose ends.

Remove the power steering pressure switch connector and remove the pressure line from the bottom of the pump, if fitted. Remove the oil cooler mounting bolt from the pump bracket, if fitted.

Refill the reservoir with power steering fluid and carry out the "Initial Operation" procedure.

Remove and cap steering pump hoses and vacuum pump vacuum line.

Remove the sender unit from engine block and plug hole in block.

Remove the serpentine belt, as outlined in the Engine Mechanical Section.

Remove and cap the oil feed line from the bottom of the vacuum pump.

Remove the lower bolt that attaches the vacuum/steering pump assembly to the engine block. Remove the nut from the steering pump attaching bracket.

Remove upper bolt from the pump assembly and remove the assembly.

Remove the mounting gasket.

Remove the steering pump to vacuum pump bracket attaching nuts.

Slide the steering pump from the bracket. Use care not to damage the internal oil seal in the vacuum pump.

Remove the two pump body spacers.

To install:

Install the two pump body spacers.

Rotate the drive gear until the steering pump and vacuum pump drive dogs align. Install the steering pump onto the vacuum pump bracket. Use care to avoid damaging the oil seal in the vacuum pump during installation. The steering pump housing and spacers must mate completely with the vacuum pump bracket.

Install the oil feed line to the vacuum pump. Tighten the oil line connection to 60 inch lbs. (7 Nm).

Install the fluid hoses to the power steering pump. Tighten the pressure fitting at the pump to 23 ft. lbs. (31 Nm).

Install and clamp the hose on the vacuum pump.

Install the serpentine belt.

Fill the reservoir with power steering fluid and perform the -Initial Operation Procedure-, located later in this section.

Start the engine and check the operation of the brakes.

Drain and siphon the power steering fluid from the reservoir.

Remove the serpentine belt, as outlined in the Engine Mechanical Section.

WARNING

Do not remove the fitting on the pump that the high pressure hose screws into. The fitting may come loose unless it is backed up using another wrench. If the fitting does come loose, it must be retightened to 40-50 ft. lbs. (57-67 Nm) before continuing. If this fitting comes out of the pump body, the internal spring and valve parts will fall out of the pump and they cannot be reinstalled properly. If this occurs the pump needs to be replaced with a new pump.

Disconnect the return hose.

Disconnect the pressure hose.

Access to remove the three bolts securing the pump to the cylinder head can be gained thru the pulley holes.

Loosen the pump bracket to the block.

Remove the 6 intake plenum bolts.

Loosen the inner cooler tube clamp at the intake plenum and remove the intake plenum.

Loosen the inner cooler tube clamp at the radiator support side and remove the tube from the vehicle.

Remove the power steering pump from the top of the engine compartment where the intake plenum was.

To install:

Set the power steering pump in place in the engine compartment from the top.

Install steering pump assembly on the engine block. Install the upper stud and bolt in bracket.

Pivot the pump down past the coolant tube and install the lower bolts in bracket.

Tighten the bolts and nut to 30 ft. lbs. (41 Nm).

Connect the hoses to the pump.

Install the serpentine drive belt.

Fill the reservoir with power steering fluid and perform the -Initial Operation Procedure-, located later in this section.

Drain and siphon the power steering fluid from the reservoir.

Remove the serpentine belt, as outlined in the Engine Mechanical Section.
